| Abstract: |
| The alloy composition and metallographic organization of eleven bronze vessels excavated from the Eastern Zhou tomb of Caibeigou at Chengyang district in Qingdao city were analyzed by handheld X-ray fluorescence spectrometer and metallographic microscope. The results show that these bronze vessels are made of Cu-Sn-Pb alloy, and contain a small amount of iron, antimony, silver and other impurity metal elements. Most of these bronze vessels are made of Pb-Sn alloy and contain high level of lead with an average value of about 17.58%. Meanwhile, all of them are foundry products without other processing. The alloy composition of these bronze vessels in the same tomb is similar, and the bronze vessels of the same vessel type in different tombs show obvious differences in the alloy technology. Some simple and badly corroded bronze vessels excavated from the Eastern Zhou tomb of Caibeigou in Chengyang district contain some free copper grains in metallographic tissues, which are closely related to electrochemical corrosion affected by the alloy composition, casting technology and buried environment. But the alloy ratio, casting technology and mechanical properties of the unearthed bronze vessels indirectly reflect that the craftsmen had mature bronze casting technology at that time and the ritual function of the bronze vessels tended to be diluted. It will provide an important scientific basis for a comprehensive understanding of the development of bronze production industry in the State of Qi in the Eastern Zhou Dynasty and the protection and restoration of bronze vessels. |
